\VILLIAM J. CONNELL, OF CHARLESTOM WEST VIRGINIA.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 377,991, dated February 14, 1888.

Application filed August 10, 1887. Serial No. 246,598. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM J CONNELL, a citizen of the United States, residing at Charleston, in the county of Kanawha and State of West Virginia, have invented certain new and useful Improvements in Window- Screens, of which the following is a specification.

My invention relates to a metallic-frame window-screen, and has for its object the allowing of the wire screen or netting to be re placed when worn by a new piece, which can readily beadjusted to the frame; and my invention consists in. features of novelty,to be hereinafter fully described, and then pointed out in the claims.

In order that my invention may be fully understood, I will proceed to describe the same with reference to the accompanying drawings,

in which- Figure I is an elevation showing my improved screen as it' appears when set in a window-frame. Fig. II is an enlarged crosssection of a window-frame, &c., showing my improved screen, the central portion being broken away. Fig. III is a modified form of the device for securing the netting or wire screen, showing the parts disengaged. Fig. IV is a similar view showing the netting set, the parts being engaged. Fig. V is a crosssection on the line V V, Fig. I, showing the catch.

Referring to the drawings, 1 represents the window-frame, having the window-sashes 2 2; and 3 3, portions of the blinds.

4 4 represent the blind-stops,'to which the guides 5 5 for the screen-sash. are secured. The guides and the screen-sash 6 are preferably made of tin or'galvanized iron. In crosssection the guide is shape, having flanges 7 turned at right angles thereto, so as to em-- brace the screen-sash on both sides. The outer edges of the flanges are turned into heads 8, to securely hold the sash.

The sash 6 is formed of metallic strips bent at right angles to fit in the guides, with the outer portion, 9, turned in a scroll, 10, which bears against a metallic fastening-strip or holding device, 1l ,which is secured by solder or other suitable means at 12 to the inner angle of the sash-strip, the inner portion, 13, ofthe latter being longer than the outer portion, and bent out at right angles thereto, and terminating with which engages the fastening-strip 11 for holding the netting or wire-screen in place. Said fastening device has a lip, 16, for engaging under the material back of the lip 15 of the sash, into the recess 17 of which the lip 16 springs. By this device the 01d screens can be removed and new ones put in with lit-- tle trouble. I

To hold the screen-sash up,I provide springs 18 on its inner side, which bear, when in looking position, against the top of the upper window-sash when the latter is down. upper sash is up, a similar" spring may hold the screen-sash down, a simple pressure on When the at 14 in a hook portion or outturned lip, 15, T I

the springonly being necessary to release the screen-sash.

The 'utilization of the window-sashes as a stop for the spring or springs of the screen does away with the cutting into the sashes or s Window-frame of mortises, notches, .&c. I

In the modification shown in Figs. III and IV the spring fastening-strip and sash are formed in one, 19 being the fastening-strip,

and 20 an angular or other groove inwhich it engages.

The top, bottom, and sides of the screensash are all constructed as set forth.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent: 1

1. In combination with strips of metal forming the top, bottom, and sides of a frame-and having spring-engaging edges lengthwise of the strips, a removable netting or wire screen secured by said engaging edges to the fra'me, substantially as set forth.

2. In combination with a window-frame,,the upper and lower sashes, a frame for netting or wire screen, provided with spring-catches on its inner side at both top and bottom adapted to automatically engage the upper sash when raised and when lowered, substantially as and for the purpose set forth.

3. A sheet-metal frame for screens,having a spring-lip, and a recess in which the lip engages to hold the netting in place, substan- IOO tially as set forth.
